I have a photon that has been working and I can still ping, signal, run health check, device doctor, particle update, etc, but I can’t flash the device. I have the same program on another Photon and it flashes properly. I have tried to flash “blink” and that won’t flash either. No matter what pro…

[image] stevegb36: I then tried to flash with the web IDE but that still doesn’t work. (“flash unsuccessful - Device not discoverable or is offline”) You have definetly targeted the correct device in Web IDE?

I tried a few more things. “particle list” shows that the device is online and has the digitalread/write analogread/write functions “particle call device_name digitalwrite D7, HIGH” turns the LED on and it stays on which confirms the Blink program is not running. (and probably not actually install…

Yes, my test set up only allows me to connect one Photon to power at a time.

That’s not what I was asking :wink: Can you show the status bar and the target drawer of your Web IDE? What is the device name and ID of the Photon you have issues with?

Hi ScruffR Here are the devices: (neither device is connected via USB to my computer - both are plugged into their own power supplies and they both show up my router as 2/4 GHz allowed devices with correct ip addresses.) [image] The device that causing the problem is “Alarm-Panel”. The screen gr…

[image] stevegb36: The screen grab below is just after power up after flashing via the USB (The events are as expected) The console events names are truncated but what I can see is that there are several events missing that I'd expect to see when flashing a device - most notable the app-hash …

Hi ScruffR The target is the correct device. ‘Test’ works but ‘Alarm Panel’ doesn’t. The events above were from powering up the Alarm-Panel device, not from flashing it. The power up events are correct (so the device is working). Here are the flash events from the ‘Test device’: (no events are pu…

This is the status bar (bottom of the window) [image] And the target (or devices) drawer pops out when you hit this icon [image] [image] stevegb36: (no events are published when flashing the ‘Alarm-Panel’) This would back my assertion that you are targeting the wrong device. You need to…

Hi ScruffR I see that I have confused the issue by mentioning the ‘Test’ device. I used the ‘Test’ device to show that the events are being displayed properly when the ‘Test’ device is being flashed and is running. I also used it to show that the router, browser, etc, are all configured properly an…

This clearly shows that you are not flashing your Alarm-Panel device but still are targeting the now offline Test device. [image] I don’t know how much clearer I can say it. In that spot you must have Alarm-Panel written - if it’s not the new application will not be delivered to any other device t…

Hi ScruffR Ok, now I understand - sorry for being so slow. What steps am I missing? I log into Particle IO. I click on Console In Devices, I click on Alarm-Panel [image] I then I click on the code </> which brings up a new window. [image] and it shows ‘Test’ - I missed that, but w…
